WASHINGTON (Reuters) - The top Democrat on the U.S. House Intelligence Committee said on Tuesday the panel should begin contempt proceedings if Steve Bannon, a former advisor to President Donald Trump, continues to refuse to return to testify in the investigation of Russia and the 2016 U.S. election.

U.S. Representative Adam Schiff said in a statement that the House of Representative committee's subpoena remains in effect and Bannon's interview has been rescheduled for next week.
